To solve the inequality \( x + 2 \frac{1}{2} < 8 \), first convert the mixed number into an improper fraction or a decimal.

In decimal form, \( 2 \frac{1}{2} \) is equal to \( 2.5 \).

Now, rewrite the inequality:

\[ x + 2.5 < 8 \]

Next, subtract \( 2.5 \) from both sides to isolate \( x \):

\[ x < 8 - 2.5 \]

Calculating the right side gives:

\[ 8 - 2.5 = 5.5 \]

Thus, the inequality is:

\[ x < 5.5 \]

Rearranging it to have \( x \) first, we can write:

\[ x < 5.5 \]

This is the final inequality.
